Application filed March 13, 1905. Serial No. 250,865.

To all whom it may concern:

Be it known that I, BURGESS SMITH, a citizen of the United States,residing at Washington, in the District of Columbia, have inventedcertain new and useful Improvements in Transfer-Presses and AttachmentsTherefor, of which the following is a specification.

My invention relates to improvements in transfer-presses; and itconsists in the constructions, combinations, and arrangements hereindescribed and claimed.

The object of my invention is to provide a simple and convenient meanswhereby all combinations and arrangements of characters can beaccurately transferred to printing-plates by the employment of a limitednumber of stock-transfer rolls, thus obviating the necessity ofmanufacturing a separate transfer-roll for each different arrangement orgroup of characters.

1n the accompanying drawings, forming a part of this application, and inwhich similar reference-symbols indicate corresponding parts in theseveral views, Figure 1 is a side elevation of a transfer-press equippedwith one embodiment of my invention. Fig. 2 is a detail view, on alarger scale, of the pressbeam and transfer-rolls shown in Fig. 1. Fig.3 is a sectional View on the line 3 3 of Fig. 2. Fig. 4 is a perspectiveview, on a larger scale, illustrating a preferred form of transfer-rollwith an index member secured to its arbor. Fig. 5 is a sectional planview on the line 5 5 of Fig. 3. Fig. 6 is a detail elevation showingspring means for retaining the roll-supporting arms in theirupperposition. Fig. 7 is a detail section, on a larger scale, showingthe adjustable attachment of a notched block to the key on theroll-support and Fig. 8 is a detail perspective view, on a larger scale,illustrating the eccentric spindle of the retaming-rollers tor theroll-support.

In the drawings I have illustrated a common form of transfer-presssimilar to that shown in J. R. Hills United States Patent No. 778,313,dated December 27, 1904, in which 1 indicates the usual press-bedcarrying a work-chuck 2 and provided with stanchions 3. A press-beam 4is trunnioned in the stanchions and provided with an angular extension 5in engagement with a cam 6, an operating-lever 7 being provided foractuating said cam to tilt the beam 4 on its trunnions.

Ahead 8, slidably mounted on the beam 4,

carries bearers 9, which latter are shown provided with an operating-face 10, substantially parallel with the surface to which the charactersare to be transferred, and with two inclined surfaces 11 leadingthereto. A screw 12 is swiveled at 13 in the beam4 and threaded at 14 inthe head 8 for adjusting the latter alon said beam, a Vernier-wheel 15being secured to said screw in cooperative relation to an index 16 onthe beam '1 or permitting accurate adjustment of the head 8 through anypredetermined distance.

A multiple-roll support 17 is provided with V-shaped rails 1.8, fittingcorresponding trackgrooves 19 in the head 8, retaining-rollers 20 beingprovided for maintaining said rails in sliding engagement with theirtracks. Each retaining-roller is rotatively secured 011 an eccentricportion 21 of a spindle 22, journaled in the head 8, any suitable means,such as a set-screw 23, being provided for locking each spindle in anydesired angular position for accurately adjusting the rails 18 to theirtracks.

A plurality of supporting-standards 24 are shown adjustably supported byscrews 25 to the adjustable roll-support 1.7 and carry at their lowerends spindles 26, on which are journaled supporting-arms 27 for thetransfer-rolls. A spring 28 engages each standard and its arms 27 fornormally maintaining the latter in their upper position, the movement ofsaid arms being limited by pins 29 on the spindles engaging slots 30 inthe arms. Each arm 27 is provided with inclined ways 31 for supportingand accurately positioning the roll-arbor, and spring means 32 arecarried by one of said arms in position to maintain said arbor againstan adjustable stop 33 on the other arm, thereby assuring axialadjustment of said arbor.

A key 34, secured. to the slidable roll-support 17, is provided withnotches 35 for engageinent with a pin or latch 36. As shown especiallyin Figs. 2 and 7, said notches are preferably formed in blocks 37,adjustably secured to the key 34 by screws 38, extending through slots39 in said blocks.

7 A notch 35 is provided in such relative position to each of thesupporting-standards 24 as to bring the transfer-roll carried by anystandard in proper position with the bearers 9 when the multiple-rollsupport 17 has been shifted to bring the notch 35, corresponding to saidstandard, into engagement with the latch 36. This construction providesa convenient means for supporting the several transfer-rolls in suchmanner that any desired one of them can be quickly shifted' intoaccurate operative position.

The latch 36 is slidably mounted in a slot 40 in the head 8 and extendsthrough an arm 41, pivotally supported at 42 on said head, pins 43 beingsecured to said latch at opposite sides of the arm 41. The pivoted arm41 is provided with a hollow angular extension 44, which carries thearmature 45 of an electromagnet 46. A spring 47 is shown engaging thepivoted arm 41 for maintaining it in its outer position against anadjustable stop 48 when the electric circuit through the magnet is open.One terminal 49 of the coils of the electromagnet is electricallyconnected to the frame of the press through a binding-post 50, and theother terminal of said coils leads through a battery or other suitablesource of electrical energy 51 to a contact 52, which is insulated fromthe frame of the press in position to be engaged by the operating-lever7 when in its normal upper position.

A sleeve 53 is provided with split ends 54 for clamping it to theroll-arbor 55 by means of straps 56. The transfer-roll 57 tightly fitssaid sleeve and is clamped against a shoulder 58 thereon by a nut 59.The roll-arbor is provided with a reduced portion 60, carrying a pin 61in position to engage notches 62, formed in the hub of an index member63. The index member is provided with characters 64, similar in kind andrelative arrangement to those on the roll. The said index characters areso positioned on the index member that a predetermined relative positionwill exist between the corresponding characters on the index member androll when the notches 62 of the index member enga e the pin 61 on theroll-arbor. A preferab e construction is that shown in the drawings, inwhich the index characters are positioned diametrically opposite to thecorresponding characters on the roll.

A notch 65 for each character on the index member is formed in theperiphery of said member for engagement by a latch 66, pivoted at 67 tothe arm 41. A tension-spring 68 is secured between a pin 69 within thehollow extension 44 and a lug 7 0, carried by the pivoted latch 66, fornormally maintaining said latch in operative relation to the notches 65.

From the above description it will be seen that when the operating-lever7 is in its normal upper position the circuit through the coils of theelectromagnet 46 will be closed, thereby energizing said magnet andcausing its armature 45 to be attracted against the tension of thespring 47. As shown especially in Fig. 3, this position of the partswill force the sliding latch 36 into engagement with whatever notch 35is in registry therewith and will swing the pivoted latch 66 intooperative relation With the notches 65 onthe index member. With an arm71 for conveniently swinging it against the tension of the spring 68 inorder to throwit out of engagement with the notches 65 when it isdesired to shift another notch into engagement with said latch.

Having thus described my invention, what I claim as new, and desire tosecure by Let ters Patent, is-' 1.
